T 0 all whom it may concern Be it known thatI, ALEXANDER L. BAx'rER, acitizen of the United States of America, residing at Masury Station, inthe county of Trumbull and State of Ohio, have invented certain new anduseful Improvements in Poured-Concrete-Cement Blocks, of which thefollowing is a specification.

This invention relates to poured concrete cement blocks. The principalobject is to provide a block having a novel face structure.

Another object is to provide a block strong in structure, convenient tomanufacture and reasonable in cost.

Another object is to provide a block with a bonding member.

Another object is to provide an air 'c1r culating system whereby the airmay be taken from the basement and carried through the walls by means ofvertical openings with convenient outlets at the upper portion of thewall.

Another object is to provide hand holds by means of oblong depressionsat ends of all but end blocks. The outer ends of these depressions alsoacting as a bonding means.

A still further object is to mold a half brick with an end surfaceextending a suitable distance beyond the surface of the side or end ofsaid blocks, or it is understood that parts or whole bricks may be used.

, The invention will be more particularly described in connection withthe specific description hereinafter to be given.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

By referring to Fig. 1 it will be seen I have provided a poured concretecement block 1 showing ends of half bricks 2 molded Specification ofLetters Patent.

therein, the end extending a desirable distance beyondsurface of block1.

- By referring to Fig. 2 it will be seen that I have a half brick 2molded therein and positioned so as to be in alinement with theprojections of the ends of the half bricks 2 showing on the side surfaceof the poured concrete cement blocks 1.

By referring to Figs. 3, 4 and 7 it will be seen the top, ends andbottom of each block are provided with curved grooves 3, said grooves 3being approximately one-half of a circle. WVhen the blocks are laid upend to end and in tiers one upon the other, these grooves 3 formcircular air chambers around the blocks 1, with the exception of thecorner blocks.

By referring to Figs. 1, 3, 5 and 7 it will be seen each block hascentral flared vertical openings 4.

By referring to Figs. 3, 4, 6 and 7 it will be seen that when ends ofsaid poured concrete cement blocks 1 are placed as shown in Fig. 11,that is each of said blocks breaking at one half the length of each ofsaid blocks, circular air channels are formed by the vertical endgrooves 3.

It will be seen by referring to Figs. 3, 4, 6, 7, 9, 10 and '11 that I,have provided half round grooves 5 which are filled with cement in thelaying process and for a wall tie.

By referring to Figs. 3, 7 and 11 it will be seen I have provided a halfround groove 6 which has a double function. When the wall, say in abasement, is started the mason in laying the second tier should leavethese grooves 6 open, and in laying the last tier at the top they shouldbe left open, thereby forming inlets and outlets, for air to circulatethrough the wall by means of the grooves 3 and the flared verticalopenings 1 and the vertical end openings.

In constructing the rest of the wall these half round grooves 6 are tobe filled with cement and act as a wall tie.

By referring to Figs. 4 and 6 it will be seen that I have provided handholds 7, the ends 8 of the same projecting over the groove 3, and isfilled with cement, thereby forming a wall tie.

By referring to Figs. 8 and 10 it will be seen that I have provided aclosing block 9 similar in construction to the block 1 with theexception of a plain end 10 which may vary in length to meetrequirements.

" In the construction ef thi s'improved build;

ing block it is obvious that ithas a Wide bearing surface and makes an eeepti neHy durable Wall.

5 By referring to Figs.'3 and l l it will seen an octagon corner 11 01"a founded eorl ner 12 may be used. n Having thus described myinvention," I claim as new and 1 0 ters Patent:
